The fact that you have the 2 sets of data makes it more complicated; since they are consistent with one another. I would seriously explore LDs, and maybe read on visual-spatial kids. Is she very creative or divergent? Maybe she just sees other things and responds in non-standard ways. My younger DD will soon be tested and I worry about this. She is very smart, but also completely outside the box thinker.
I am certain (although I can't prove it with IQ tests) that my brothers and I are gifted and my sister is not. She DOES have some LDs, but it is not just that. However, in her case, there were no "wow" moments. With your dd, you are seeing other things. With my sister, I remember how hard it was for her to learn colors and counting, her vocabulary has never been precise, etc.
I would not discard the info from the tests but I would also not take it as an absolute.
